I work in the industry making hardware and software for large scale commercial and grid scale storage.

There are several challenges with this, safety, thermal runaway, and life cycle of the asset which has a limited amount of cycles.

Also the architecture of the system for the AC inverters and the DC side can come from very different places in the supply chain and aren’t as vertically integrated leaving you in a position where you can’t actually make this work without compromising something in the supply chain. That being said we are talking about a LOT of energy in these systems and to dissipate that much heat you’d need a load bank.

Lost my 635 day streak last week, offered £5.99 or something to repair it. I was pretty gutted but actually on reflection, the gamification just added undue stress. Duolingo is great for vocab and repetition, it was only with a tutor that I really became conversational.

Also agree. However, I do yearn to relive the days where one can load up a web page and start reading content, without being jarred by pop-ups and ads that inadvertently move the content post load (which of course happens 3 seconds later..).

Amazon Sidewalk 5 years ago

"Amazon does not charge any fees to join Amazon Sidewalk"

Not to the end customer anyway. To organizations and developers building on top of the APIs...

Completely against this idea though its a shame its not... "Get paid for hosting a network using the devices you purchase from us"*

Lastly, it is a cost albeit negligible to the end user who installs the device (power, bandwidth, etc).

*I know it wouldn't amount to anything but its a interesting way to think about it.

We too are also doing something similar. We've just started the move to timescale for real-time energy and sensor data from industrial assets. We have a single customer with about 10TB of data and growing from 2 years worth of real-time monitoring which is stored in a mixture of table storage and SQL. Timescale on PG seems like blessing for our future plans :)

There is definitely a need for better technology for start-ups in this space.

Having said this, I don't know what this product does from the website.

We pay ~$80 a month for 2 users to a financial planning application that integrates with our accounts (Xero) and it works well. Our revenue is 7 digits annually.

As a start-up founder, I appreciate what you're trying to do with your model but I kind of like, you know, just knowing the fixed costs regardless of our revenue.

Hey! Maybe mfreed could answer this but how does this affect users of Timescale as part of Azure's Managed Posgres service, is this something that will still continue to be available?

Since setting up a business in 2016, I needed to better understand how to build a business:

Principles by Ray Dalio - I found this really motivating to ensure our business sticks to and has a set of principles that evolve based on mistakes made (sounds obvious).

Hard Thing About Hard Things by Ben Horowitz - I loved listening to this (audible) because being a CEO can be lonely and hearing other peoples thoughts and advice based on their experience (that you can relate to) is really uplifting.

2018 has been a great year for us and I do think these books have helped me get through the roller coaster that is building a technology startup.

Vanadium batteries are very promising, however the energy density is the main issue here. Lead Acid batteries have a better ratio however obviously lead is toxic and it requires more than just lead. The fact that Vanadium batteries capacity is limited to just the size of the tank (slight oversimplification) is a positive for sure, their life span is also a positive factor. It also, while classed as toxic, is not classed a seriously hazardous.

I don’t think it’s fair to say they ignored advances in modern programming languages. There are opinionated reasons for the omission of generics and they do make sense in the overall architecture of the language. At the end of the day it’s about trade offs and ultimately my opinion is that, having written a lot of both C# and Go, I can see the pros and cons of feature sets. Its about choice of tool for the solution in mind. I’m happy with that.
